For rifles in 30 caliber, this 165 grain #2140 Hollow Point Boat Tail bullet, which is patterned after the world-famous 168 grain MatchKing bullet, was designed for shooters who desire a hunting version of that famous MatchKing. It is slightly “harder” than its 165 grain Spitzer Boat Tail counterpart and will give superior penetration and good expansion on medium game with excellent accuracy. This is a good medium-weight bullet choice for shooters of 30 caliber magnum rifles who desire a bullet that will not deform at the point. For handguns chambering 30 caliber cartridges, this 165 grain #2140 bullet is “hard” and will expand in medium to large game only when driven at a muzzle velocity of 2500 fps or more, which is achievable in the 308 Winchester cartridge in the Remington XP-100 handgun or a similar combination. It can, of course, be used for handgun silhouettes or other target purposes.
